How often do you update your iPad?

I am going to try to make the switch to an 10.5 inch IPad Pro. I have a MacBook but want to give it a shot. It does everything that I need and more... I will test it for a month before I sell my MacBook..

It can replace a laptop, but it can’t be compared against one.
The iPP 10.5” is great and I think you’ll love it!

I'm not on a cycle honestly. I get a new iPad when I "need" one. My 12.9 is still working flawlessly. I imagine I've got a few more years on that. No need to waste the money on a new one when the current one works just fine. For me, my iPad is seen in a similar light as my computers.

I upgraded from my iPad 2 last year to an iPad Air 2. I would have liked to get the iPad Pro but after discussing this with a very helpful sales associate at our local Apple Store, I decided that the Air 2 would fit my needs perfectly, and I have no regrets. I have no immediate plans to upgrade (unless I win the lottery, and then heck yeah). As long as my Air 2 behaves, and stays relevant (based on being able to update to the latest iOS), I don't foresee me making a change.
